still can't get LB working on my gtx 580. reformatted and tried both the CRU method and the original method, screen just goes haywire after enabling 3d or rebooting after setting the resolution with CRU.

Try a displayport connection. Has anyone run Lightboost on this monitor via a GTX580 successfully? I forgot someone here said they had the same scrambled screen but got rid of it somehow. Are you sure you are using the correct timings? Look's like something that would occur if the timings were bad.

i've tried latest stable, latest beta, and the drivers that came on the cd. don't have a displayport cable, but I guess I could try ordering a displayport to DVI cable and I can give another dual link dvi cable a shot, jeri said he was having those problems but his end all fix was using CRU. i've done the timings manually, and I've also imported the bin file that everyone's been using for CRU, so I really doubt it's that, I've done it so many times the margin for that kind of error is so slight.

even when I set up a custom resolution just in NVIDIA's drivers I get the same scrambled screen using the timings you provided.
